I have a requirement where I need to loop through certain steps in RSAT while testing. I created a purchase order and recorded it through task recorder and loaded the recording in RSAT. While creating po you can add multiple lines so that you can add multiple items. This are steps I recorded and this is the steps in excel parameter file:

I have another excel file which has Item number, Site Warehouse and Quantity.
Now from step 13 to 18 I need to loop through to add item numbers, site, warehouse and quantity from this file. I can add these items manually in the excel parameter file by copying the values and adding it. But what if I have 100s or even more records. Doing that would be really time consuming and not feasible. Is there any way we can loop when test case is running, so that based on records the add line step will repeat again? Any kind of help is appreciated.
